RESUMEN
BACKGROUND: Preparticipation screening for conditions associated with sudden cardiac death (SCD) is required in college athletes. Previous cost analyses used theoretical models based on variable assumptions, but no study used real-life outcomes. OBJECTIVE: The purpose of this study was to compare disease prevalence, positive findings, and costs of 2 different screening strategies: history and physical examination alone (H&P) or with an electrocardiogram (H&P+ECG). METHODS: De-identified preparticipation data (2009-2017) from Pacific-12 Conference institutions were abstracted for cardiovascular history questions, cardiovascular physical examination, and ECG result. Secondary testing, cardiac diagnoses, return to play outcomes, and complications from testing were recorded. The costs of screening and secondary testing were based on the Centers for Medicare & Medicaid Services Physician Fee Schedule. RESULTS: A total of 8602 records (4955 H&P, 3647 H&P+ECG) were included. Eleven conditions associated with SCD were detected (2 H&P only, 9 H&P+ECG). The prevalence of cardiovascular conditions associated with SCD discovered with H&P alone was 0.04% (1/2454) compared to 0.24% (1/410) when ECG was added (P = .01) (odds ratio 5.17; 95% confidence interval 1.28-20.85; P = .02). Cost of screening and secondary testing with H&P alone was $130 per athlete and in the ECG-added group was $152 per athlete. The cost per diagnosis was $312,407 in the H&P group and $61,712 in the ECG-added group. There were no adverse outcomes from secondary testing or treatment. CONCLUSION: H&P with the addition of ECG is 6 times more likely to detect a cardiovascular condition associated with SCD than without. The addition of ECG improves the cost efficiency per diagnosis by 5-fold and should be considered at college institutions with appropriate resources.
